5 Questions
What are the two components of a node in a linked list?
Data and Next Pointer
How is a linked list different from an array in terms of memory storage?
The memory locations of a linked list are not contiguous, unlike an array.
What is the purpose of the head node in a linked list?
The head node points to the first node in the list and is used to access the linked list.
Why does the last node in a linked list point to NULL or nullptr?
It indicates the end of the list and is known as the tail node.
How can linked lists be represented in memory using arrays?
Linked lists can be represented in memory by using two arrays known as INFO and LINK, where INFO[K] contains information of the element and LINK[K] contains the reference to the next node.
Study Notes
Linked List Overview
- Linked list stores data sequentially but with non-contiguous memory locations
- Unlike arrays, linked lists can store data of different data types
- Node in a linked list consists of Data and Next Pointer components
- Data component holds the actual value associated with the node
- Next Pointer component stores the memory address of the next node in the sequence
- The linked list is accessed through the head node, which points to the first node
- The last node in the list points to NULL or nullptr, indicating the end of the list
- The last node is known as the tail node
- Linked lists can be represented in memory using two arrays: INFO and LINK
- INFO[K] and LINK[K] contain information of an element and the next node respectively
- Representation of linked list in memory involves using two arrays: INFO and LINK
- Traversing a linked list is a common operation on linked list data structure
